Explore our cutting-edge machinery designed for complex profile and tube extrusion, integrating Taiwanese structural durability with top-tier automation control loops.
Founded in 2002, BAOD EXTRUSION has dedicated more than two decades to designing, manufacturing, and marketing top-tier plastic extrusion machinery. Rooted in 18 years of pioneering development by our Taiwanese parent company (KINGSWEL GROUP), we established our mainland China production hub in Shanghai in 1999, which later grew into our modern state-of-the-art facility in Jiangsu.
Our operation integrates robust Taiwanese precision engineering standards with highly responsive, cost-effective mainland China supply chain systems. This ensures that every line we ship satisfies strict parameters for durability, efficiency, and automated process management.
By merging Taiwanese engineering roots with continuous local innovation, we offer a comprehensive technical ecosystem that streamlines installation, reduces commissioning time, and maximizes production uptime.
From complex medical catheters to thick-walled industrial profiles, our solutions are engineered to deliver reliable results under round-the-clock operating conditions.
Insights into the thermal dynamics, mechanical stability, and engineering criteria that drive modern profile extruding machinery.
Custom plastic profile extrusion involves pushing molten polymer through a specialized die to produce intricate, consistent shapes. Unlike symmetrical round tubing, irregular profiles face uneven flow velocities and cooling shrinkages. Maintaining dimensional stability requires exact control over melt pressure, shear rates, and downstream calibration.
To prevent profiles from collapsing before solidification, advanced systems use dry-vacuum calibration tables. Sizing plates match the profile's exact design, while vacuum channels draw the polymer face against the cooling metal surfaces. This system prevents deformation from internal thermal stresses, holding tolerances within fractions of a millimeter.
The core of an extrusion system is the single screw extruder (such as BAOD's SJ Series). Depending on whether processing TPU, PVC, Polycarbonate, or filled materials, the screw design adjusts compression ratios, barrier flights, and mixing sections. L/D ratios of 28:1 to 32:1 are common to achieve complete plastification without overheating the compound.
In today's global supply chain, precision plastic profiles are vital components in automotive, medical, building, and lighting industries. Procurement teams face a challenging balance: maintaining tight tolerances (often within 0.05mm for medical catheters) while reducing the Total Cost of Ownership (TCO). High-efficiency production requires line layouts that minimize startup scrap, run smoothly, and integrate multiple secondary processes downstream.
European and American manufacturers are increasingly looking to China for advanced extrusion technology. The reason is the rapid evolution of China's machinery sector. Suppliers like BAOD EXTRUSION provide European-standard engineering, Siemens PLC interfaces, and durable mechanics at a competitive cost, allowing companies to quickly recoup their initial investments.
Manual adjustments during extrusion are becoming obsolete. Industry 4.0 standards demand closed-loop control. Laser OD gauges and online wall-thickness scanners send real-time dimensions back to the PLC. This system automatically adjusts the puller speed and screw rotation speed to correct any variations, ensuring high consistency throughout long production runs.
For co-extrusion setups (e.g., dual-durometer weather seals combining rigid and flexible materials), synchronous control of both extruders is critical. A central control system enables easy monitoring of all temperatures, feed rates, melt pressures, and line speeds from a single touch screen.

How our profile and tube extrusion machinery adapts to meet the demanding requirements of various industries.
Medical tubes must follow strict quality control guidelines. Extruding medical catheters (e.g., dual-lumen or triple-lumen tubes) requires very consistent material feed and steady air pressure inside the lines. BAOD's medical-grade lines are built with sanitary-compliant stainless steel, and feature high-precision control loops that keep dimensions stable even at high speeds.
Modern electric vehicles demand specialized plastic components to reduce weight and ensure long-term performance. Our multi-layer PA smooth/corrugated tube lines supply reliable fuel lines and cooling systems, while our co-extrusion systems produce high-quality weatherstripping. These seals prevent water leakage and help reduce cabin noise.
With the expansion of 5G and high-speed fiber optic networks, micro-duct systems are in high demand. We manufacture specialized lines for HDPE silicone core tubes, co-extruding a low-friction silicone layer inside the duct. This allows contractors to blow fiber optic cables over long distances without damaging the glass fibers.
LED lighting requires consistent plastic housings. Our PC/PMMA lampshade extrusion lines produce clear, frosted, or double-color optical profiles. Precise temperature control ensures clarity without yellowing or structural warping.
